据美国 PNAS(《国家科学院科研报告集》)1994年12月6日报道,一些新的研究工作正在澄清氧的毒性改变的本来面目。氧的毒性改变指的是,如果氧变成损伤性自由基,则会使接触它的动物滋生疾病或缩短寿命。美国南方卫理公会大学的索奥尔(R.S.Sohal)和艾加华尔(S.Agarwal)把家蝇一生中氧化剂诱导的 DNA 损伤的累积与平均生命期联系起来,并发现,只要氧化的DNA 集结越多,家蝇存活的时间 According to the PNAS (Proceedings of the National Academy of Sciences) report of December 6, 1994, some new research work is clarifying the true nature of oxygen toxicity changes. A change in oxygen toxicity means that if oxygen becomes a damaging free radical, it can cause disease or shorten the life of the animal that comes in contact with it. RSSohal and S.Agarwal of Southern Methodist University linked the cumulative oxidant-induced DNA damage and average life span of housefly life and found that as long as oxidized DNA The more time to build up, house flies survive
